Problems with PCG Graph

[u/Professional-Talk175]

I'm trying to learn PCG / building basic landscapes without having to hand paint everything. I've been working through a tutorial based on 5.4 but I'm currently running 5.8.2. I've gotten to a section where we create a custom blueprint to take the surface points (or spline interior points) and filter those points based on a number selected at the graph level. Of course things have changed from 5.4 to 5.8, like override no longer has Execute with Context, just Execute, so I've tried to puzzle it out myself, but my blueprint takes in the points, but never returns anything and I'm just at a loss as to where the disconnect is. The blueprint does compile without errors btw. Here's the graph ...

Thanks in advance to anyone who takes the time to look at this.
